Question

A roller is made by joining together two cones at their vertices O. It is kept on two rails AB and CD which are placed asymmetrically (see figure), with its axis perpendicular to CD and its centre O at the centre of line joining AB and CD (see figure). It is given a light push so that it starts rolling with its centre O moving parallel to CD in the direction shown. As it moves, the roller will tend to:

Answer:

C

Solution:

As roller moves forward radius of circle of left cone on track AB decreases. Thus right cone travel more distance compared to left and roller turns left
